To build your own STT (speech-to-text) with a local model and and modify it, just ask Claude code to build it for you with this workflow.

F12 -> sox for recording -> temp.wav -> faster-whisper -> pbcopy -> notify-send to know what’s happening

I found a Linux version with a similar workflow and forked it to build the Mac version. It look less than 15 mins to ask Claude to modify it as per my needs.

F12 Press → arecord (ALSA) → temp.wav → faster-whisper → xclip + xdotool

Thanks to faster-whisper and local models using quantization, I use it in all places where I was previously using Superwhisper in Docs, Terminal etc.
